Chicago, IL. — As the world increasingly looks towards sustainable solutions for building and construction, Phius, the smartest path to a zero-carbon environment, announced the launch of its Passive Building Foundations training course.

This comprehensive, self-paced training course provides a baseline knowledge of Phius and passive building for a broad audience of individuals in the AEC sector. These include marketers, developers, policymakers, bankers, investors, real estate agents, homeowners, and property managers interested in adaptable, resilient, healthier homes and buildings. Join Phius to explore more about the new training at the free Passive Building Foundations Training Webinar on May 21, 2024. Register HERE.

Phius, a non-profit organization, puts passive building principles into practice in a way that is cost-effective, quality-assured and climate-appropriate with plans customized to fit each project’s needs. Phius Certification is the leading standard for energy-efficient construction in the world, requiring buildings to meet specific performance criteria, including airtightness, insulation and ventilation. Phius Certified buildings are proven to use 40-60 percent less energy than code-built buildings at minimal to no upfront cost premium.

“We are thrilled to offer this new accessible entry point into the world of passive building,” said Phius Co-Founder and Executive Director, Katrin Klingenberg. “Passive Building Foundations training empowers individuals with the knowledge and credentials to make informed decisions and communicate the benefits and value of energy-efficient building practices vital for mitigating the effects of climate change – creating resilient buildings of the future.”

Unlike traditional building certification programs, the online program is designed for those with little to no technical background in building science and does not require prior experience. The self-guided training offers maximum flexibility, consisting of approximately eight hours of interactive content spread across nine modules. Topics covered include:

  • Phius Background and Goals
  • Building Science Fundamentals
  • Core Passive Building Principles
  • Phius Standards and Certification Paths
  • Business Case for Phius Projects
  • Policy and Passive Building Growth
  • Real-World Case Studies
  • Decarbonization and the Future of Passive Building

Upon completing the course and passing a one-hour exam, participants earn the Phius Associate designation. This demonstrates a foundational knowledge of passive building principles and positions graduates to successfully communicate about the benefits of passive building for our communities and the climate.

Passive Building Foundations is ideal for anyone looking to expand their understanding of passive building and improve their ability to market, sell and communicate about passive buildings as a differentiated product. Whether you’re a seasoned developer seeking to integrate sustainable practices into your projects, a policymaker striving to enact meaningful change, or homeowners and buyers curious about the benefits of living in a passive home, this course is for you. 

Registration for the Passive Building Foundations opens May 21, 2024. Visit for more information and to register today.
